WAREHOUSE-CRANE.

To all whom it may concern:

Be it known that I, Gnonen H. H LETT, a

.. citizen of the'United States, and a resident of Cleveland, in the eounty of Cuyahoga and State of Ohio, have invented certaln new .and useful. Improvements in VVarehouse- C-ranes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in warehouse cranes, theobject being to provide a crane adapted to move lengthwise the warehouse and provided with a movable or telescopic boom or booms, adapted to be pro-' jected at the ends of the main crane through openings in the sides of the building, so as to overhang, say a vessel at one side and freight cars at the opposite side, whereby freight within the warehouse may be loaded into the vessel or cars, or freight in the vessel or cars can beunloaded and stored in the warehouse, or freight ina car or vessel can be unloaded from one and loaded into the other without rehandling.

My invention consists in a crane having a telescopic boom, and a traveling trolley adapted to travel on said boom and also on the main crane bridge.

My invention further consists in a gauntree crane mounted within a, warehouse'and provided with rigid end extensions, terminating within the side walls of the building, a boom telescoping with one of'said end extensions and adapted to be projected through openings in the side of the building, and a trol-- ing the hatehways of a boat at one side and ear tracks at the other side, and Fig. 3 is an enlarged view in section on the line B-B, of Fig. 1..

1 represents a gauntree crane mounted within a warehouse 2 and on a gallery 3 withi Specification of Letters Patent.

Patented June 3, 1919.

Application filed OctoberlD, 1918. Serial No. 257,586.

in the latter so as to permit free passage to,

from and across the main floor of the building without being interfered with by the movements of the crane, and also leavmg the entire main floor for storage purposes. 6

This gallery may be located at one side of the building as shown in dotted lines, or it may be in the center, as shown in full lines in Fig. 1. or instead of a gallery it may have simply supports 4 for the runway 5 of the crane 1. The main bridge or crane is preferably of skeleton form, open, at its bottom and both ends, with integral end extensions 6 projecting beyond the bridge carrying members 7, and terminating adjacent the slde walls of the house 2.

This crane is adapted to travel lengthwise the house and is provided at each end with a movable boom 8 adapted to be projected through, and beyond the ends of the extensions 6, and

through openings in the side walls of the house 2 so as to overhang say a vessel at one side of the house and freight cars at the other side. These booms are moved by any suitable gearing, and like the main crane l, are open at their undersides as clearly shown in Fig. 3, so as to permit the trolley 9 and its hoist cables to have free and unrestricted travel therein.

The booms 8 are preferably supported on rollers 10 which move between track rails 11 secured to and within the main crane bridge 1, and they are provided internally at the sides, with the tracks 12 on which the flanged wheels 14 of the trolley 9 run. trolley is also provided with a second set of carrying wheels 15, located in a plane below the wheels '14, and adapted to engage and travel on rails 16 secured to the main crane bridge 1 at the sides and near 'the ower edge of the latter. The rails I the booms bear a fixed relation to tl1e3.&ails' 6 on the main crane bridge, and as two ets of trolleyrarrying wheels 14 and 15 The 90 ear fixed relation to each other and to their 1 speetive track ways, so that when the trolley enters the booms from the main bridge it will be supported on both trackways until it passes beyond the end of the bridge and will thenbe supported solely on the boom and as it leaves the boom on its inward travel it will be wholly carried by the main bridge. With this construction the trolley can travel from one boom to the bridge and lengthwise the bridge to the other boom so that after the booms have been set, the trolley can travel from a point outside of the building at either side, to the other side, and thus unload freight from, say a vessel -moored in a slip at one side of the house and deposit it directly on cars on tracks at the opposite side of the house, or can deposit itwithin the warehouse, or can take freight from the warehouse and load it directly onto cars or boats as the case may be.

In the drawing I have shown the main crane mounted on a gallery at the center of the warehouse, and have provided each berth or bay unde'rthe gallery with a small traveling crane 17 hence by providing the gallery with openings as shown in Fig. 2,

the-main crane 1' can be permanently set over the hatchways of a boat .and any freight that is to be stored in the warehouse can be lowered through any one of the hatches or openings in the gallery. to the floor, and then picked up by one of the' I smaller cranes l7 and carried to any point covered by the travel of such crane;

By providing each house with a series of the exact construction and arrangement of parts herein shown and described, but

Having fully described my invention what I claim as new and desire to secure by Letmain cranes, the latter can be set to-workover. ahatchway or car,'but whennecessary,

the booms can be drawn into themain crane and the latter 'then' moved longitudinally of the house so as -to' deposit its load at any desired point covered by the travel of the main crane.

The trolley on the main crane is preferably provided with an operators car con-- taining the controllers for the several mo-, tors,'so that the operator may always be within sight of the lo'adcarried by the trolley, and the house 2, ispreferably provided v with sliding for closing up the openings in the sides thereof throughwhich the booms project,

It is videnf' that many slight changes might be resorted to in the relative arrangement' or parts shown vand described without departing from the spirit and scope of my invention. fI-Ienceel; would have it under- I stood-that'I- do. wish to confine'inyself to terS-Patent, is

1. In a warehouse plant, the combination of a house having openings through which a crane member may be projected so as to handle freight outside of the house, runways within the house, the said runways being elevated to permit of free access to and from said main floor under them, a crane mounted on said runways, one end of saidcrane terminating-within the house adjacent theside having openings therein, a .boom telescoping with said end andvadapted to be projected through said openings, and a trolley adapted to travel on the crane bridge and also on the boom.

2. In a warehouse plant, the combination of a house, having openings through which a crane member may be projected so as to handlefreight outside. of the house, runways within the house the said runways inglelevated to permit free access to-and from the floor under-them, a crane proper mounted on said runways, the ends of said crane terminating within thehouse, and one end terminating ad acent the side of the house having the openings therein, a boom telescoping with said end and adapted to be projected through said openings, a trolley adapted to travel on tracks within the boom and also on tracks within the crane proper, and a second crane located below the main crane and adapted to travel lengthwise the house, for picking up and transporting.

In testimony whereofll have signed this
